OpenVPN for TiVo HD

Here's my current work on OpenVPN for the TiVo HD. It should be possible to run it on any TiVo, you just have to recompile the appropriate kernel with CONFIG_TUN=y. For some reason, the TiVo crashed when the tun/tap driver was compiled as a module.

OpenVPN and supporting libraries were compiled cleanly using the latest mips-TiVo-linux toolchain.

Here's the ReadMe:

-----------------
2. Installation |
-----------------
Copy the Binary folder to your TiVo. For these instructions, I will assume
the files are in /var/hack/openvpn. Perform the following commands:
mount -o remount,rw /
cd /lib
tar xzf /var/hack/openvpn/openvpn_libs.tgz
cd /platform/lib/modules
mv bcmenet.o bcmenet.orig
cp /var/hack/openvpn/bcmenet.o bcmenet.o
cd /var/hack/openvpn/
dd if=/dev/hdaX of=vmlinux_backup.px
dd if=vmlinux-Gen06-openvpn.px of=/dev/hdaX
** REPLACE hdaX WITH YOUR KERNEL PARTITION **
reboot
Note: The openvpn_libs may not be required. You are welcome to try to run the
openvpn binary without the libs installed. It seems to work on my TiVo, so it
may work on yours as well.
-------------------------------------------
3. Kernel Modifications and OpenVPN Usage |
-------------------------------------------
The included kernel is an extension of Jamie's netopt-ext3 kernel based on the kernel
sources provided by TiVo for the 9.4.1 OS. It will work on 9.x and 11.x. In addition to
patches included by Jamie, it also has support for Bridges (via brctl) and TUN/TAP
devices.
The OpenVPN command works the same way it would on any other platform. Configuration
of OpenVPN is your own responsibility.

Thanks for this. Does this also include the tweak to /proc/sys/net/core/rmem_* that you mentioned in your earlier thread?
